Science KS2: Teeth - how they help animals eat

Zoe uses graphics to explain how different animals have teeth suitable for their diet, whether carnivore or herbivore, and how the variety in human teeth allows us omnivores to chew up the wide variety of food we eat.

An experiment with an egg left in vinegar demonstrates how our teeth our softened by the acid created by sugar, and why brushing our teeth is important.

This short film is from the BBC series, Amazing Me.

Teacher Notes

You could recreate the experiment that’s in this short film, with an egg left in vinegar for three days, an egg left in cola for three days, and an egg left in water for three days.

Compare the results and see what happens. Can your pupils explain the results?

Pupils could compare the teeth of omnivores, carnivores and herbivores.

Look at real case-studies; such as rabbits, cats and humans.

Draw the different types of teeth, and label them to see how they're different.
